Help -poor cold starting, wayward rev counter and backfiring
Posted: Sun Jan 27, 2008 12:26 pm
Hi,
My car's been a bit tricky start from cold since I picked it up in the New Year, but I figured this was probably just me not knowing how to start these old 911s properly. But having had chance to use it a bit more over this weekend, I think the ignition circuit needs some sorting.
The rev counter's also whacky at best, and tends to drop to zero when I lift off the throttle which I think is almost certainly related.
Today, the car also started idling poorly and cutting out at traffic lights and backfiringwhen on no throttle. When it backfires, the rev counter also jumps back up the dial.
I thought it might be condenser, but looking at it, I think mine doesn't have one (1972 T with Zenith carbs).
The points look okay but the rotor and distributor cap look a bit worn, so I figure the first thing I'll do is change those.
Are these the kinds of things I can just pick up in Halfords? (I'm guessing not).
Any other tips? From reading a few posts, I'm really hoping that it's not a problem with the CDI.
The car starts okay when hot and runs fine when on the throttle.
Cheers, Ross.
